Code P20FD RAM Description

The P20FD diagnostic trouble code (DTC) refers to the "Reductant Pump 2 Control Circuit Low" in the vehicle's selective catalytic reduction (SCR) system. The reductant pump is responsible for supplying the diesel exhaust fluid (DEF) to the SCR system, which helps reduce harmful emissions by converting nitrogen oxides (NOx) into nitrogen and water vapor. When the control circuit for the reductant pump 2 is detected to be operating at a low voltage or not functioning properly, this code is triggered.
